Analysis of information sources in references of the Wikipedia article "Ron Weasley" in Galician language version.
[...] really enjoyed writing the Ron/Lavender business, and the reason that was enjoyable was Ron up to this point has been quite immature compared to the other two, and he kind of needed to make himself worthy of Hermione....he had to grow up emotionally and now he's taken a big step up.
There’s a lot of immaturity about Ron, and that’s where a lot of the humor [sic] comes from.
Ron is the most immature of the three main characters, but in part seven he grows up. He was never strong footed, people see him mostly as Harry's friend; his mother had actually wanted a girl and in the last book he finally has to acknowledge his weaknesses. But it's exactly that which makes Ron a man.
